Origins of Letterpress Printing in Poland

The press reaches Central Europe

Johannes Gutenberg’s method of casting individual metal letters and locking them into a reusable form spread rapidly from Mainz after the 1450s. Within two decades, workshops had been established in Strasbourg, Cologne, Venice, and several other cities. The technology moved along trade routes, carried by journeyman printers who could set up a press wherever a patron or merchant provided capital and premises.

The earliest documented printing activity in the territory of the Polish Crown dates to the 1470s. Kasper Straube printed in Kraków by 1473 or 1474, producing a short calendar — the Almanach Cracoviense — which is among the earliest surviving examples of printing anywhere in Central Europe. The city’s position as the capital of the Jagiellonian kingdom, with its university founded in 1364, made it a natural location for a press: there was an educated readership, a clerical demand for liturgical texts, and access to funds from the church and nobility.

Early Kraków workshops

Through the late fifteenth century, several printers operated in Kraków, often under the patronage of the Jagiellonian court or the bishop’s household. Jan Haller established a press by the early 1500s that became one of the most productive workshops in the region, printing liturgical books, chronicles, and humanist texts. Haller imported typefaces from Venice and Nuremberg, adapting them with additional characters for Polish orthography — in particular the characters ą, ę, ó, and ł, which had no counterpart in the Latin type inventories of German or Italian founders.

Florian Ungler and Hieronim Wietor, active in the first decades of the sixteenth century, further expanded the range of Polish printing. Ungler printed the first books substantially in the Polish language, working alongside the scholar Stanisław Zaborowski, who provided vernacular texts at a time when most scholarly and religious publishing still favoured Latin.

Material and technical conditions

Establishing a press in fifteenth-century Kraków required importing several specialist materials. Type metal — an alloy of lead, tin, and antimony — was cast in hand moulds, with each letter cast individually at the press or sourced from type foundries abroad. The wooden press itself, modelled on the screw presses used in winemaking and papermaking, was fabricated locally once a model was available. Ink was prepared from linseed oil boiled with lampblack; recipes circulated among printers but were treated as trade knowledge.

Paper came primarily from mills in Bohemia, Silesia, and later from Polish mills established in the sixteenth century. The quality and size of available paper sheets shaped the formats that Polish printers could produce: folios and quartos were common; smaller formats required more precise press adjustment and higher paper costs per page of text.

The church as first patron

The earliest Polish presses operated largely on commissions from the church and from the Jagiellonian university. Missals, breviaries, and liturgical calendars represented guaranteed sales in quantities that justified the upfront cost of setting and presswork. Secular texts — chronicles, legal documents, humanist treatises — followed as the reading public expanded through the sixteenth century. The Reformation accelerated vernacular printing across Central Europe; Polish presses responded by producing confessional literature in Polish, contributing to the standardisation of written Polish as a literary language.

Spread beyond Kraków

By the mid-sixteenth century, presses had been established in other Polish cities, including Gdańsk, Poznań, and Lublin. Each regional centre had different patrons and audiences: Gdańsk’s press served a largely German-speaking mercantile community; Poznań’s output reflected the interests of the local nobility and the Poznań academy. The diversity of regional printing activity over the following two centuries produced a varied body of material that is now held in the collections of Polish national and university libraries.
